2 Biology and Ecology

Taxonomic Hierarchy and Taxonomic Standing According to Eschmeyer et al. (2017), Bullockia maldonadoi (Eigenmann 1920) is the valid name for this . It was originally described as Hatcheria maldonadoi.

From ITIS (2015):

“Kingdom Animalia Subkingdom Bilateria Infrakingdom Deuterostomia Phylum Chordata Subphylum Vertebrata Infraphylum Gnathostomata Superclass Osteichthyes Class Subclass Neopterygii Infraclass Teleostei Superorder Order Siluriformes Family Subfamily Bullockia Species Bullockia maldonadoi (Eigenmann, 1928)”

Size, Weight, and Age Range From Froese and Pauly (2017):

“Max length : 5.7 cm SL male/unsexed; [DoNascimiento et al. 2014]”

2

Environment From Froese and Pauly (2017):

“Freshwater; demersal; pH range: 6.0 - 7.0; dH range: ? - 15. […]; 16°C - 26°C [assumed to be recommended aquarium temperature] [Baensch and Riehl 1991]”

Climate/Range From Froese and Pauly (2017):

“Subtropical; […]”

Distribution Outside the United States Native From Froese and Pauly (2017):

“South America: Chile.”

From Dyer (2000):

“Bullockia maldonadoi Is another endemic taxon to the Chilean Province (ARRATIA et al.1978) […]”

Introduced No records of Bullockia maldonadoi introductions were found.

Means of Introduction Outside the United States No records of Bullockia maldonadoi introductions were found.

Short Description A description of Bullockia maldonadoi was not found.

Biology From Link and Habit (2015):

“Areas with sandy substrate. Juveniles inhabit in rivers with current velocity <0.09 m/s and adults <0.9 m/s [Arratia 1983; Scott et al. 2007; Penaluna et al. 2009]”

“Benthic, insectivorous, nocturnal”

Human Uses From Froese and Pauly (2017):

“Fisheries: of no interest”

Diseases Information on pathogens of Bullockia maldonadoi was not found.

Threat to Humans From Froese and Pauly (2017):

“Harmless”

3 Impacts of Introductions

No records of Bullockia maldonadoi introductions were found, therefore there is no information on impacts of introduction.

6 Climate Matching Summary of Climate Matching Analysis The climate match for Bullockia maldonadoi was high along the Pacific Coast and low everywhere else. The Climate 6 score (Sanders et al. 2014; 16 climate variables; Euclidean distance) for the contiguous United States was 0.015, medium. Oregon and Washington had individually high climate scores, California had a medium individual climate score. All other states had low individual climate scores.

Figure 3. Map of RAMP (Sanders et al. 2014) climate matches for Bullockia maldonadoi in the contiguous United States based on source locations reported by GBIF Secretariat (2017). 0 = Lowest match, 10 = Highest match. Counts of climate match scores are tabulated on the left.

The High, Medium, and Low Climate match Categories are based on the following table:

Climate 6: Proportion of Climate Match (Sum of Climate Scores 6-10) / (Sum of total Climate Scores) Category 0.000≤X≤0.005 Low 0.005

7 Certainty of Assessment The certainty of assessment is low. Very minimal information was available for Bullockia maldonadoi. No records of introductions were found.

8 Risk Assessment Summary of Risk to the Contiguous United States Bullockia maldonadoi is a species of catfish native to Chile. It is insectivorous and nocturnal. The history of invasiveness is uncertain. There were no records of introductions found, therefore there is no information on impacts of introduction. The climate match is medium; the Climate 6 score was 0.015. Oregon and Washington had high individual state climate scores. The certainty of assessment is low. Very minimal information was available for Bullockia maldonadoi. The overall risk assessment category is uncertain.

Assessment Elements  History of Invasiveness (Sec. 3): Uncertain  Climate Match (Sec. 6): Medium  Certainty of Assessment (Sec. 7): Low  Remarks/Important additional information No additional remarks.  Overall Risk Assessment Category: Uncertain
